Monty_girl,
I had been on various depression meds for over 10 years and went off over a year ago; I felt they were numbing me and of course they didn't prevent depression all the time because they can't. So, I wanted to see what it was like without them. It's been hard at times, but no harder than when I was on the meds. I am now working with a psychologist for deep and lasting treatment and relief. It feels better to be off the meds, although things have surfaced that had been kept supressed/repressed by the meds.
It is good to realize our therapists are human, too. Mine has told me several times "I don't have all the answers" and "I am not always right". I tend to put her way high on a pedestal! (I think when I do that it is because I not only want her to have all the answers, be right all the time, but also somehow to do the work or make it magically easier).
It sounds like you have a really good relationship with your therapist and I hope you will talk to him more about why he thinks you should go back on your meds: those things may be the things to work on right now. It could be the things the meds numbed for you are surfacing and need addressed.
